Ethernet Interface
The Ethernet Modem may be connected to a PC via an Ethernet connection. Also, it is possible to
connect multiple PC devices to a single Modem. The multi-PC configuration is transparent to the PC
users and is analogous to a multi-PC configuration on a normal Ethernet LAN. Check with your Service
Provider if multiple IP addressing is required for your particular configuration. The distinct advantage of
the Ethernet Modem is that it connects to any device that has an Ethernet interface. This makes it ideal
for small businesses that have a mix of devices, such as Unix machines, Apple Computers, etc. IP
addresses can be assigned to the devices dynamically via a DHCP server, or as Fixed IP assignments, or
Point-to-Point Protocol Over Ethernet (PPPoE).
Multiple Interface Environments
When a PC has an internal interface (for example, a Wireless Ethernet interface) in addition to the
Ripwave Modem, you should do the following:
• If the wireless connection is not required, disable the internal wireless connection
• If the built-in wireless connection is required for local networking and wireline Ethernet is used via
the Ripwave Modem for Internet connection, change the interface metric configuration so that the
wireline interface’s default gateway is used. (See your Operating System’s User Guide.)
Routers
Neither the Navini Ripwave Monitor nor the Navini Diagnostics software will work if it goes through a
router.
Battery
Older Ripwave Modems gave the user the option of buying an 1800 mA Li-Ion battery. With the optional
battery, the user could be connected to the Internet anytime and anywhere there is RF coverage without
the need for a power outlet. The Modem battery was rated to provide 30 minutes to 90 minutes of use
without recharging (depending on activity).
